preparation example 13,1
[0036] Preparation Example 13, Preparation of 19-isopropylidene-14-acetylandrographolide (abbreviated as AP5)
[0037] Dissolve 5g of andrographolide (abbreviated as AP), 20mL of 2,2-dimethoxypropane and a catalytic amount of p-toluenesulfonic acid in 100mL of acetone, heat and reflux overnight, extract the reaction mixture with ethyl acetate, and the organic layer is sequentially washed with saturated NaHCO 3 Wash with saturated brine, anhydrous Na 2 SO 4 After drying, concentration, and silica gel column chromatography, 3,19-isopropylidene andrographolide (abbreviated as AP2) was obtained as a white solid. 1g AP2 dissolved in 10mL Ac 2 O, heated to reflux for 2 hours, the reaction mixture was extracted with ethyl acetate, the organic layer was successively water, saturated NaHCO 3 Wash with saturated brine, anhydrous Na 2 SO 4 dry. AP5 was obtained as a white solid by silica gel column chromatography. The molecular formula is: C 25 h 36 o 6 .
